application filed fictobcr 3%, 191+".- Selifil No. 869,411.

To all whom it may concern Be it known that I, Hemmer S. Elnorrrrnnffi a citizen of the United States, and resident of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain nee snd useful Improvements in Water- Hesters, of which the following is a specification. r v

' This invention relates to instantaneous Waiter-heaters, and more particularly to the circulation coil thereof, and one object, is to provide simple and ellicient means for supporting theooil within the heater casing.

.13 further object is to simplify the constir-notion and reduce the'number of parts and connections most liable to disorder by making the support tubular and utilizing it for passing water which flows through the coil.

In the preferred adaptation, a supporting element is disposed transversely of the coil and sustained by the casing with its ends of non-communicating tubular form for passing cold Water to the coil and hot water therefrom; In addition to the element just referred to, the invention in its preferred form includes an improved supporting cnnection with an intermediate portion of the coil. also improved means for sustaining or partially sustaining the coil from above.

in the accompanying drawings, Figure 1 is an elevation of a Water heater coil errsnged in accordance with the invention, heir of the sectional casing being removed and the casing crown and in intermediate" portion of th-coil shown in section. Fig. 2 is a view in top plan with portions of the casing crown shown in section. Fig. 3 illustrates a portion of the inclosing casing.

Referring to the drawings, the invention is preferably embodied in a yerticelly divide'd casing with the opposite edges of part,

2 thereof formed with notches 3, and with casing pert l adopted to joint with port 2 for inclosing the upright circulation coil crown 6 of conventioneljorm is provided with the usual top opening Y.

The coil is sustained primarily by the riser pipe dhvhich extends upwardly through tlriecoil with its upper end connected to the u") or coil extremit b fitting 9. The lower end of pipe 8 is secured to the transverse supporting element 16, the laterally extend ing tubular ends 11 and 12 of which are adapted to rest in casing notches 3,beingv 'With the supply and distribution pipes, not

shown.

The coil here shown is 111 the form of a series of spools, and the smaller convolutions of each spool may be additionally sup ported by the flanged plate 14 adjustably secured to riser 8. For sustainingthe coil from above, a bolt 15 may project upwardly from fitting 9 through and be. secured to a spider 16 which bridges crown opening 7 The invention provides a compact and rigid support for the circulation coil, and by utilizing the supporting means for the cold and hot Water connections the parts and fitting are reduced toe minimum. To re more the coil it is only necessary to open casing part l and release bolt 15 and the entire coil and its supporting means may be taken out.

i The gas burners commonly employed heneaththe circulntion'coi'l are not shown as they may be variously arranged, and it will also be understood that-the casing and other conventional, ports of the apparatus not im medintely involved in the present invention may be variously embodied.

I claim: 1. In a water heater, the combination of an upright circulation coil, a tubular sup r, the support cxits lower end in communication therewith and at its upperv end in communication with the upper portion of the coil.

3. In a Water heater, the combination of an uprightcirculation coil, :1. support disposed transversely of the .coil and having non-communicating tubular, portions, nd communicating connections between the respectir e tubular parts of the support and the upper and lower portions of the coil.

4 In awaterheater, the combination of an upright circulation coil, a transverse support having tubular non-communicating end portions extending laterally from the coil, and communicating connections between the respective tubular end portions of the support and the upper and lower extremities of the coil.

5. In a water heater, the combination of an upright circulation coil, a transverse support beneath the coil and having non-communicating end portions extending laterally therefrom, a pipe extending upwardly through the coil and at its lower end' connected to one of the tubular portions of the support and at its upper end connected to theupper portion of the coil, and a communicating connection between the lower portion of the coil and the other tubular portion of the support 6. In a water heater, the eombinationof an uprightcirculation coil, a tubular support beneath the coil, an inlet pipe extendin from the support upwardly through the C011- and in communication with the upper por-.

tion of the latter, a support above the coil, and a connection between the inlet pipe and the last mentioned support.

7. In a water :heater, the combination of an upright circulation coil, and an upright coil-supporting pipe within the coil andiin communication therewith.

8. In a water heater, the combination of an uprightcirculation coil, ail-upright pipewithin the coil and in communication therewith, pipe supporting-means, and a's pporting connection between an intermediate portion of the coil and said pipe.

9. In a water heater, the combination of a casing, an upright circulation coil therein, a support disposed transversely of the coil tions of the coil.

coil in opposite directions and rigidly connected to each other at their a'dgacent ends and in communication with di erent por- 11. In a water heater, the combination of an upright vertically divided casing with one part of the casing adapted to support a circulation coil andztbeother part fitting and adapted to close the coil-supporting part, the coil-supp the other casing part adapted to close said notches, an upright circulation-coil within the casing,'and a coil-supporting member extending across thecoil and secured thereto with the opposite ends laterally from the coil and entered in said casing notches.

12. In a water heater, the combination of an upright vertically divided casing with one part of the casing adapted to sup ort a. circulation coil and the other pa t tting and adapted to close the coil-supporting part, thecoil-supporting casing part formed with notches in its vertical edges and with the other casing part adapted to close said netches,fan upright circulation coil within the casing, a coil-supporting member ex.- 'tendingacross the coil and he ving non-cont municating'tubular ends extending laterally therefrom and removably entered in the casing notchesfor supporting the coil, and ini'et and outlet circulation connections between orting casing part formed 1 with notches in its vertical edges and with thereof projecting the respective tubular ends of the supporting member and the 'coil.

In testimony whereof I afiix my signature,
